Services performed

In-depth inspection of a connector tunnel in accordance with TOMIE manual and the SNTI manual of the U.S. Department of Transportation - FHWA.

Description

Inspected tunnel connects two quarries at the Luck Stone Corporation Fairfax plant. The tunnel crosses beneath the Lee Highway (US Route 29), in a North-South direction. Built ca. 1975, the tunnel is partially unlined and in rock; approx. 190 feet long and approx. 22 feet wide and 22 feet high. As the Northern quarry side is already exhausted, the tunnel is rarely used with just one or two transits per day.
Dr. Sauer & Partners performed an in-depth inspection of a connector tunnel; assessed the tunnel condition and provided remedial measures.

Geology

The prevalent rock type of the tunnel is diabase. The rock mass is moderately jointed, with closely to very closely spaced joints. The rock is slightly weathered.
